Outline
To study the fiber characteristics of insulating wood pulp during the beating process and their impact on the properties of electrolytic capacitor separator, fibers with different beating degree were prepared using a Valley beater to prepare electrolytic capacitor separators, and their mechanical properties and electrical properties were tested. The results show that with the increase of beating time, the beating degree of the insulating wood pulp increase, leading to the decrease of fiber length and the increase of brooming degree. With the increase of beating degree, the surface pore structure of the prepared separators significantly decreases, while the density, tensile strength, and electric strength of the separators increase. In addition, with the increase of beating degree, the liquid absorption performance of the separators decreases, and the equivalent series resistance (ESR) per unit thickness increases.
